Jenkinsfile - How to detect destination of pull request

Question

so I have a jenkinsfile where I have my pipeline. I would like to be able to distinguish between a pull request which is going to the master and pull requests going elsewhere. I have found example code for detecting pull requests - something like this:

env.BRANCH_NAME.startsWith('PR-')

But is there any way to find out the target of the pull request from some env. variable?

Answer 1

As per https://yourjenkinsurl/pipeline-syntax/globals:

CHANGE_TARGET
For a multibranch project corresponding to some kind of change request, this will be set to the target or base branch to which the change could be merged, if supported; else unset.
